“…2 eV [41][42][43] , but the E g of rGO is generally lower than that of NVO; thus, the bandgap narrowing in a synthesized composite is not surprising. The band gap decrease upon adding rGO to known photocatalysts, such as ZnO or TiO 2, was also reported in the literature 44,45 . The positive influence of rGO on photocatalytic activity has been recently reviewed by Mondal et al 46 .…”

“…Significantly, the intensity of the mentioned peaks reduces with an increment in ZnS amount in composite samples. A prominent dip is visible in the spectrum range at 2300 cm −1 which can be considered as a mark of C-H groups and again reduces with an increase in ZnS amount [18]. Several characteristic peaks for ZnS can be observed at around 612, 799 and 2075 cm −1 in composite samples R 2 and R 3 .…”

“…Here, I D and I G are the intensities of the corresponding D and G peaks. C(λ) is a functional factor that depends on wavelength, and La is the average crystallite size of sp 2 domains, which is approximately 16.26 nm in this case, indicating the formation of nano-rGO crystallites [18,37]. Raman spectra for composite samples (R 2 and R 3 ) are presented in figures (b) and (c).…”
